独脚金属(Striga spp.)及列当属(Orobanche spp.和Phelipanchce spp.)杂草是世界范围内对农业生产危害严重的根寄生杂草,主要依靠寄生茄科、豆科、谷类等作物获得水分和营养。根寄生杂草种子只有在合适的萌发诱导物(如独脚金内酯)刺激下才能萌发。文章从根寄生杂草的分类、分布及危害,种子萌发剂类型及适用范围,种子萌发剂独脚金内酯的生物合成及分离鉴定,根寄生杂草种子萌发诱导剂的作用机制以及种子萌发过程中激素间协同调控作用等方面进行了综述,并展望了种子萌发剂设计筛选及其在根寄生杂草化学防控中的潜在应用前景。
Striga spp. And Orobanche spp. And Phelipanchce spp. Are the most parasitic weeds in the world that are detrimental to agricultural production and rely mainly on crops such as parasitic Solanaceae, legumes and cereals Get water and nutrition. Root parasitic weed seeds germinate only when stimulated with suitable germination inducers such as strigolactone. This paper reports the classification, distribution and damage of root parasitic weeds, the types and application of seed germination agents, the biosynthesis and identification of strigolactones, the mechanism of seed germination inducer and the germination of seeds The synergism between hormones and other aspects of the process were reviewed, and the prospect of seed germination agent design and screening and its potential application prospects in chemical control of root parasitic weeds were prospected.
